"She's not just paranoid, she's terrified,'' her father said.
The alleged filming and theft took place between February 1 and last Friday, according to court documents.
The complainant's father said he was now concerned members of his "very loyal" family would seek retribution.
Seeing the student in the dock had also left him seething.
What made the alleged offending so sickening was the fact the family had embraced the defendant, he said.
"The kids idolised him ... I treated him like a son."
Since the weekend's revelations, the student's belongings had been packed up and sent to the polytechnic.
Among them was his passport, which Judge Turner ordered he surrender to authorities by 4pm today.
Other bail conditions included:
• To live at a specified Dunedin address on a 6pm-7am curfew.
• To present himself at the front door if requested by police.
•Not to go within 100m of the complainant's home.
•Not to have contact with persons under 16.
• Not to possess or use a device capable of taking still or moving images.
